摘要
采用季胺化反应—复分解或质子化两步法设计合成了系列阴离子为BF4-或CF3SO3-的咪唑类、吡啶类的功能化离子液体.系列功能化离子液体与三氟甲磺酸耦合催化1-丁烯/异丁烷的烷基化反应,并获得了C8选择性81.1%,TMP/DMH=8.36及RON值为95.3的良好催化效果,耦合催化剂在不降低催化活性的条件下可循环使用6次.
A series of task specific ionic liquids based on imidazolium and pyridine with BF4-/CF3SO3- anion were synthesized through quaternary ammonium metathesis and protonation reaction. The above ionic liquids coupled with triflic acid were applied to catalyze the isobutane alkylation. Excellent alkylate quality with high C8 selectivity （81.8%）, the ratio TMP to DMH at 8.36 and high research octane number 95.3 were obtained by tuning the type and content of ionic liquids. The coupled catalyst can be recycled for six times without significant loss of activity.
